本发明涉及海水测量技术领域，提供一种温盐深仪及具有温盐深仪和搭载平台的配合装置。其中温盐深仪包括：减速组件，包括减速舱本体；电路组件，包括电路舱本体；漂浮组件，其包括机架，电路舱本体与机架的一端连接；测量探头，包括探头本体，至少一第一解锁组件，设置在减速舱本体与电路舱本体之间，在温盐深仪进入探测水域后，用于自动分离减速舱本体和电路舱本体；和/或，至少一第二解锁组件，设置在机架与探头本体之间，在温盐深仪进入探测水域后，用于自动分离探头本体与机架，在温盐深仪朝向探测水域掉落并进入到探测水域后，能够将减速舱本体与电路舱本体以及探头本体与机架进行自动分离，无需工作人员操作即可实现两个连接体之间的分离。

The invention relates to the technical field of seawater measurement, and provides a temperature-salinity-depth instrument and a matching device with the temperature-salinity-depth instrument and a carrying platform. The temperature-salinity-depth instrument comprises a deceleration assembly which comprises a deceleration cabin body; the circuit assembly comprises a circuit cabin body; the floating assembly comprises a rack, and the circuit cabin body is connected with one end of the rack; the measuring probe comprises a probe body and at least one first unlocking assembly, is arranged between the deceleration cabin body and the circuit cabin body, and is used for automatically separating the deceleration cabin body from the circuit cabin body after the temperature-salinity-depth instrument enters a detection water area; and/or at least one second unlocking assembly which is arranged between the rack and the probe body and is used for automatically separating the probe body from the rack after the temperature-salinity-depth instrument enters a detection water area and automatically separating the deceleration cabin body from the circuit cabin body and the probe body from the rack after the temperature-salinity-depth instrument falls towards the detection water area and enters the detection water area. And the separation between the two connecting bodies can be realized without the operation of a worker.
